Core Viewpoint - The northern regions of China, particularly North China, are experiencing an unusually prolonged rainy season, with significant rainfall exceeding historical averages, attributed to various climatic factors [2][3][4]. Summary by Sections Rainfall Patterns - The rainy season in North China began on July 5, 2023, which is 13 days earlier than the average, marking the earliest start since 1961 [2]. - As of August 25, 2023, the cumulative rainfall in the monitoring area of North China was 131% higher than the average [2]. Climatic Influences - The excessive rainfall is linked to abnormal sea temperatures in the equatorial Pacific, a strong and shifted subtropical high-pressure system, typhoon activity, and geographical factors [3]. - The subtropical high-pressure system has been notably strong and has shifted northward, allowing for continuous moisture transport from the ocean to northern regions [3]. Weather Systems and Topography - The influence of Typhoon "Zhu Jie Cao" has contributed additional moisture to North China, enhancing rainfall [4]. - The topographical features, such as the Taihang and Yanshan mountains, have caused forced uplift of warm, moist air, leading to increased precipitation through condensation and convection [4]. Climate Change Context - The record-breaking rainy season is seen as a localized manifestation of climate change, highlighting the need for improved climate adaptation and response capabilities to handle extreme weather events [4].

Summary of Key Points Core Viewpoint - The article discusses the weather patterns associated with the "End of Heat" solar term, indicating that while temperatures may begin to decline in northern regions, southern areas are likely to continue experiencing high temperatures due to the influence of the subtropical high-pressure system [1]. Group 1: Weather Patterns - Most regions still experience high temperatures during the "End of Heat" solar term, particularly in southern areas such as Shanghai, Changsha, Guangzhou, and Hangzhou [1]. - The subtropical high-pressure system may retreat southward but can still maintain stability in southern regions, leading to clear skies and rapid ground warming [1]. - High humidity in southern areas exacerbates the feeling of heat, making it feel more oppressive [1]. Group 2: Regional Differences - In northern regions, the temperature difference between day and night increases, which can lead to the phenomenon of "one autumn rain brings a cool breeze" [1]. - Rainfall in northern areas during this period tends to have a "cool and moist" characteristic, while southern rainfall is influenced by warm and humid air currents from the subtropical high-pressure edge [1]. Group 3: Agricultural Implications - The increase in temperature difference during the "End of Heat" solar term is beneficial for the accumulation of dry matter, leading to faster maturation of crops [1]. - Farmers are advised to pay close attention to weather forecasts to optimize their harvest activities during this critical period [1].
